As shown in fig. 1 or 2, the vehicle lamp module 4 includes a plurality of lamp sets 11, each lamp set 11 including at least one LED unit 12; the triggering device 1 is used for generating a lamp triggering instruction according to user operation; the vehicle body area control device 2 is connected with the trigger device 1 and used for sending a vehicle lamp control signal according to a lamp trigger instruction; the vehicle lamp area control device 3 is connected to the vehicle body area control device 2 and each LED unit 12, respectively, and is configured to receive a vehicle lamp control signal and periodically control the lighting of the vehicle lamp modules, in each period, the LED units 12 in the multiple lamp sets 11 are controlled to be lit in a pipeline manner, and for each lamp set 11, the LED units 12 in the lamp sets 11 are controlled to be lit to a first brightness and switched from the first brightness to a second brightness, where the first brightness is higher than the second brightness.
Specifically, when the triggering device 1 generates the lamp triggering instruction according to the user operation, it sends the lamp triggering instruction to the vehicle body area control device 2, and further in response to the lamp triggering instruction, the vehicle body area control device 2 sends the vehicle lamp control signal to the vehicle lamp area control device 3, and the vehicle lamp area control device 3 periodically controls the vehicle lamp module 4 to light, compared with the existing method of lighting by using a flow method, the vehicle lamp system 10 of the embodiment of the invention adds a control strategy of different levels of brightness of a gradual lighting type on the basis of lighting the vehicle lamp module 4 by using a flow method, that is, the vehicle lamp area control device 3 controls the lighting sequence and time interval of each lamp set 11 in each cycle of lighting of the vehicle lamp module 4, so as to achieve the effect of lighting by a flow method, and at the same time, the vehicle lamp area control device 3 controls the LED units 12 in the lamp sets 11 to light to a first brightness and switch from the first brightness to a second brightness, as shown in fig. 3, a schematic diagram of lighting each lamp set step by step is shown, wherein the lamp area control device 3 controls the brightness of the lamp set 11 by adjusting the current, and for each lamp set 11, it controls the lighting of a higher initial brightness defined as brightness 1, that is, it controls each lamp set 11 to light gradually from the off state to the first brightness, in this process, the rising trend of the current is nonlinear as shown in fig. 4, this lighting manner gives a respiratory sensory experience, the effect is softer, and when the brightness of the lamp set 11 reaches the steady state, the brightness of the lamp set 11 is controlled to be lower than the brightness 1 defined as brightness 2, that is, the lamp set 11 is directly switched to the second brightness when reaching the steady brightness, so that for the whole lighting process, a highlight light spot is gradually lighted from the head end to the tail end, and different brightness grades make the whole lighting process just like a star, therefore, the dynamic meteor lamp effect which is more striking and easier to identify is achieved, and the warning performance is improved.
In an embodiment, the triggering device 1 may be a turn signal lever or an emergency warning light switch.
In an embodiment, the lamp area control device 3 may preset a master control sequence, so that in the process of lighting the lamp module 4, the LED units 12 are sequentially lit according to the master control sequence to achieve the effect of controlling the lighting of the lamp module 4 in a running-water manner, for example, as shown in fig. 2, a plurality of LED units 12 are sequentially arranged along the direction a to B, which are 1, 2 … … n, n +1, and n +2, and each 3 lamps are taken as one path to form the lamp group 11, and along the direction a to B, the lamp groups are sequentially taken as the first path to the nth path, which are e1 and e2 … … en, each path of the lamp group 11 is connected to the lamp area control device 3 through a connector, and then the lamp area control device 3 is connected to the vehicle body area control device 2 through a connector. Therefore, when the vehicle body area control device 2 receives the operation signal of the user, the vehicle lamp area control device 3 sends the vehicle lamp control signal to drive the LED unit 12 to light up step by step after the vehicle lamp area control device 3 receives the signal.
The transmission connection between the lamp module 4 and the lamp Area control device 3, and the transmission connection between the lamp Area control device 3 and the vehicle body Area control device 2 may be a hard wire, a Local Interconnect Network (LIN) wire, a Controller Area Network (CAN) wire, or a wireless signal, and the connection manner is not limited.
In the embodiment, as shown in fig. 3 or 4, the lamp area control device 3 is further configured to control all the LED units 12 to switch to the off state after the LED units 12 in all the lamp groups 11 are turned on to the second brightness in each period.
The following describes an example of the process of lighting the lamp module according to the embodiment of the invention with reference to fig. 2 to 4, and the specific steps of lighting the lamp module in one period T1 are as follows. As shown in fig. 4, one period is T1 ═ T3+ T4, and one period is once lighting, and the flicker frequency thereof needs to satisfy (90 ± 30) times/min, T3 < 1s, and T1 < 1.5 s.
As shown in fig. 2 and 4, first, the first path of lamp set e1 is controlled to be gradually lit from an off state to a high state, that is, the brightness of the first path of lamp set e1 reaches the first brightness, the lighting time t1 reaches a steady state when the current reaches I1, the first brightness keeping time is t2, then the current is switched to I2, that is, the brightness of the first path of lamp set e1 reaches the second brightness, the second brightness keeping time is (t3- (t1+ t2)), and the corresponding lighting effect is shown in step (1) in fig. 3; furthermore, when the first path of lamp set e1 becomes normal brightness, that is, the first path of lamp set e1 maintains the second brightness, the second path of lamp set e2 is controlled to be gradually lighted from the off state to a high brightness, that is, the brightness of the second path of lamp set e2 reaches the first brightness, the lighting time t1, and when the current also reaches I1, the current is switched to I2, that is, the brightness of the second path of lamp set e2 reaches the second brightness, and the corresponding lighting effect is shown in step (2) in fig. 3, by the first brightness retention time t2, and then the current is switched to I2, that is, the brightness of the second path of lamp set e2 reaches the second brightness, and by the second brightness retention time (t3-2(t1+ t 2)); furthermore, when the second bank of lamps e2 becomes normal brightness, that is, the second bank of lamps e2 maintains the second brightness, the third bank of lamps e3 is controlled to be gradually lighted from the off state to a high brightness, that is, the brightness of the third bank of lamps e3 reaches the first brightness, the lighting time t1, and when the current also reaches I1, the current is switched to I2 by the first brightness keeping time t2, that is, the brightness of the third bank of lamps e3 reaches the second brightness, and the corresponding lighting effect is shown in step (3) in fig. 3 by the second brightness keeping time (t3-3(t1+ t 2)); in this way, each path of lamp set 11 is sequentially turned on step by step along the direction from a to B until the (n-1) th path of lamp set becomes normal brightness, that is, the (n-1) th path of lamp set maintains the second brightness, the n-th path of lamp set en is controlled to be gradually turned on from the off state to the high brightness, that is, the brightness of the n-th path of lamp set en reaches the first brightness, the turning-on time t1 is reached, when the current also reaches I1, the current is switched to I2 for the first brightness retention time t2, that is, the brightness of the n-th path of lamp set en reaches the second brightness, and the corresponding turning-on effect is shown in step (n) in fig. 3 for the second brightness retention time (t3-n (t1+ t 2)). So far, the LED units 12 are all lit at the second brightness, that is, the lamps shown in fig. 3 are all in the normal lighting state, and as for the whole lighting process of the lamps, a highlight light spot is gradually lit from one end to the other end in the sense of flowing stars, the lighting process is more striking, more glaring and more warning compared with the existing product.
Further, when the LED units 12 are all lit at the second brightness, that is, the lamps are all in the normal lighting state, and the total lighting time reaches t3, the lamp area control device 3 controls all the LED units 12 to be immediately turned off, and the turning-off time is kept at t4, so that the lighting process of the lamp module 4 in one cycle is completed.
It should be noted that, the above is only one cycle as an example, the cycle of the lamp module 4 is repeated when the lamp module is cyclically turned on, and when the user operation is stopped halfway, the lighting effect is immediately stopped, and after the operation signal of the user is received again, the cycle of the lamp module is turned on again.
Through the above steps, in each period, the first path of lamp set e1 to the nth path of lamp set en are gradually lighted in a flowing water form, meanwhile, in the embodiment of the invention, a step-by-step highlight lighting process is added in the normal flowing water lighting process, that is, each path of lamp set 11 is controlled to reach the first brightness from the off state, and then the first brightness is maintained for a certain time and then is reduced from the first brightness to the second brightness, compared with the existing method for controlling the current from 0 to ISteady stateAnd the ascending trend is linear, then the vehicle lamp brightness is controlled in a manner of decreasing to 0, as shown in fig. 4, the vehicle lamp system 10 according to the embodiment of the present invention controls the vehicle lamp brightness in a manner of controlling the current to rise from 0 to I1, and the ascending trend is nonlinear, then decrease to I2, and finally decrease to 0, the effect is softer, and the vehicle lamp module 4 is controlled to start with a highlight, gradually transmit to the end, and gradually light from one end to the other end in the overall lighting process,the whole lighting process is as if the meteor runs, and the effect of a more striking and easier-to-identify dynamic meteor lamp is achieved. Therefore, the vehicle lamp system 10 according to the embodiment of the present invention not only prompts others in a more striking manner, but also improves the visual appearance effect of the function, thereby achieving the effect of taking both the function and the aesthetics into consideration.
According to the vehicle lamp system 10 of the embodiment of the invention, based on the vehicle lamp modules 4, when the triggering device 1 generates the lamp triggering instruction according to the user operation, the lamp triggering instruction is sent to the vehicle body area control device 2, the vehicle body area control device 2 sends the vehicle lamp control signal to the vehicle lamp area control device 3 according to the lamp triggering instruction, and then the vehicle lamp area control device 3 periodically controls the vehicle lamp modules 4 to light, in each period, the LED units 12 in the plurality of lamp groups 11 are controlled to light in a flowing manner, for each lamp group 11, the LED units 12 in the lamp groups 11 are controlled to light to a first brightness and switch from the first brightness to a second brightness, and the first brightness is higher than the second brightness, compared with the flowing manner, the vehicle lamp system 10 of the embodiment of the invention increases a step-by-step highlight lighting process in the normal flowing manner, that is, that the vehicle lamp area control device 3 controls the lamp groups 11 to start, the transmission step by step is up to the end to it is a highlight light spot from head end to light gradually to see in the sense organ, makes the process of whole lightening draw through like meteor, makes the effect that the car light was lightened more striking, and changes the discernment, improves the warning nature.
